VI. Structure Overview
The circuit breaker is of compact structure and characterized by modularization. The contact system is enclosed between two insulation
baseboards with partition structure, and the contacts of each phase are partitioned to form independent chambers. The intelligent controller,
operating mechanism, manual and electric operating mechanisms are arranged in front of each other in turn to form their own independent units.
If one of the units fails, the unit can be completely removed for the replacement (see Figure 6 and Figure 7).
